ABSTRACT

In the past decades,a dramatic development of navigation technology in orthopaedic surgery has been witnessed. By assisting the localization of surgical region,verification of target bony structure,preoperative planning of fixation,intraoperative identification of planned entry point and direction of instruments or even automated insertion of implants,its ability and potential to reduce operation time,intraoperative radiation,surgical trauma,and improve accuracy has been proved. However,in contrast to the widespread use of navigation technology in arthroplasty,orthopaedic tumor,and spine surgery,its application in orthopaedic trauma is relatively less. In this manuscript,the main purpose is to introduce the technical principles of navigation devices,outline the current clinical application of navigation systems in orthopaedic trauma,analyze the current challenges confronting its further application in clinical practice and its prospect in the future.

ABSTRACT

Purpose: Bone repair aims to restore the anatomical, biomechanical, and functional integrity of the affected structure. Here we study the effects of ascorbic acid (AA) and epidermal growth factor (EGF) applied in a single dose and in combination on the repair of a noncritical bone defect model. Methods: Twenty-four rats were divided into four groups: an intact G-1 control group, and three groups that underwent a noncritical bone defect in the right tibia: G-2 treated with AA, G-3 treated with EGF, and G-4 treated with AA in combination with EGF. After 21 days of treatment, rats were sacrificed, the tibias were dissected and a destructive biomechanical analysis of three-point flexion test was performed in a universal testing machine; the values of stiffness, resistance, maximum energy, and energy at maximum load were statistically compared. Results: G-3 and G-4 recovered the biomechanical properties of strength and stiffness of an intact tibia 3 weeks after their application. Not so the energy and energy at maximum load. For G-2, only the stiffness of an intact tibia was recovered. Conclusion: EGF and AA-EGF applied to a noncritical bone defect in the rat tibia favors the recovery of bone resistance and stiffness.

ABSTRACT

INTRODUCCIÓN El error técnico más común durante la reconstrucción del ligamento cruzado anterior (LCA) es la ubicación incorrecta del túnel. Es incierto si un túnel tibial mal ubicado puede corregirse en el intraoperatorio. OBJETIVO Medir el desplazamiento del injerto de tejido blando con tornillos de interferencia tibial.MATERIALES Y MÉTODOS Estudio experimental ex vivo en 28 rodillas porcinas. Se cosechó el tendón flexor de la extremidad posterior, que fue duplicado y dimensionado para que pasara a través de un túnel tibial mal posicionado. Las muestras se dividieron en 4 grupos según el cuadrante de entrada (anterior [A], posterior [P], medial [M], o lateral [L]) de un tornillo de interferencia tibial de 9 mm con relación al injerto. Se ubicó una regla milimétrica en la meseta tibial, la cual fue fotografiada con una cámara EOS T6 (Canon Inc., Ota, Tokio, Japón), y la imagen fue digitalizada, y puesta en escala a tamaño. La distancia y dirección de los desplazamientos del injerto se midieron con Adobe Photoshop CC 2019 (San José, CA, EEUU). Se analizaron las diferencias medias entre los grupos por análisis de la varianza (analysis of variance, ANOVA, en inglés) unidireccional. El análisis estadístico se realizó con el programa Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY, EEUU), versión 25.0 (p ≤ 0,05)).RESULTADOS La distancias medias de los desplazamientos del injerto fueron similares en todos los grupos: A ­ 4,4 mm; P ­ 4,6 mm; M ­ 4,5 mm; y L ­ 4,3 mm, sin diferencias estadísticamente significativas (p = 0,894). Las direcciones medias de los desplazamientos del injerto también fueron similares entre los 4 grupos: A ­ 176° (desviación estándar [DE]: ± 15,4°); P ­ 165° (DE: ± 16,6°); M ­ 166° (DE: ± 12,1°); y L ­ 169° (DE: ± 10,6°). No se encontraron diferencias estadísticamente significativas (p = 0.42).CONCLUSIONES Independientemente del cuadrante de entrada, se observó un desplazamiento constante del injerto hacia el lado opuesto cuando el tornillo tibial alcanzaba la superficie articular. Relevancia clínica: el tornillo tibial mal posicionado puede corregirse en el intraoperatorio con fijación proximal en cuadrante específico, y debe alcanzar la superficie articular para generar un desplazamiento efectivo del injerto. Sin embargo, no podemos predecir la magnitud de error en todos los túneles mal brocados, que debe ser evaluada caso a caso.


BACKGROUND The most common technical error during anterior cruciate ligament (ACL) reconstruction is incorrect tunnel placement. It remains unclear if a misplaced tibial tunnel may be corrected intraoperatively. AIM To measure the displacement of soft-tissue grafts with tibial interference screws. MATERIALS AND METHODS Ex-vivo experimental study in 28 porcine knees. The flexor tendon of the posterior limb was harvested, doubled and sized to fit through a 9-mm misplaced tibial tunnel. The specimens were divided into 4 groups according to the quadrant of entry (anterior [A], posterior [P], medial [M], or lateral [L]) of a 9-mm tibial interference screw in relation to the graft. A millimetric ruler was placed at the tibial plateau, which was photographed with a an EOS T6 (Canon Inc., Ota, Tokio, Japan) camera, and the image was digitalized and scaled to size. The length and direction of the graft displacements were measured with Adobe Photoshop CC 2019 (San José, CA, US). The mean differences among the groups were analyzed through one-way analysis of variance (ANOVA). The statistical analysis was performed using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY, US) software, version 25.0 (p 0.05) RESULTS The mean lengths of the graft displacements were similar among the groups: A ­ 4.4 mm; P ­4.6 mm; M ­ 4.5 mm; and L ­ 4.3 mm, without statistically significant differences (p » 0.894). The mean directions of the graft displacements were also similar among the groups: A ­ 176° (standard deviation [SD]: 15.4°); P ­ 165° (SD: 16.6°); M ­ 166° (SD: 12.1°); and L ­ 169° (SD: 10.6°). No statistically significant differences were found (p » 0.42). CONCLUSIONS Regardless of the entry quadrant, constant graft displacement to the opposite side was observed when the tibial screw reached the articular surface. Clinical relevance: a misplaced tibial tunnel may be corrected intraoperatively with a quadrantspecific screw, which must reach the articular surface to produce an effective graft displacement. Nevertheless, we cannot predict the magnitude of this error in every poorly-drilled tibial tunnel; it should be assessed case by case.

ABSTRACT

Flatfoot could be divided into flexible flatfoot and rigid flatfoot. Flatfoot with symptoms is called symptomatic flatfoot, surgical treatment is required if conservative treatment is not effective. Subtalar arthroereisis is a minimally invasive procedure which has been used for many years with good results in flexible flatfoot, however, still has many controversial points. Controversial points focus on indications and contraindications, optimal age, subtalar arthroereisis alone or not, efficacy and safety of absorbable material implants, and implant removal. The paper reviewed and summarized the use and controversies of subtalar arthroereisis in symptomatic flatfoot as follows:the best indication for subtalar arthroereisis was pediatric flexible flatfoot syndrome and aged from 10 to 12 years old was optimal age for treatment;tarsal coalitions with flatfoot and adult flatfoot were relative indications. Stiff flatfoot, joint laxity, and subtalar arthritis were contraindications;obesity and neurogenic flexible flatfoot were relative contraindications. The correction ability of subtalar arthroereisis alone was limited, and it's combined with other procedures depending on patient's situation. The safety and efficacy of absorbable material implants had been reported. Routine removal of the implant was not necessary, the main reason of which was tarsal sinus pain.

ABSTRACT

OBJETIVO Proporcionar una sinopsis exhaustiva y un análisis de los estudios biomecánicos sobre la magnitud y distribución de la presión en la interfase tendón-huella de las roturas del manguito rotador, informadas en la literatura en los últimos cinco años. MÉTODOS La investigación se realizó de acuerdo con los métodos descritos en el Manual Cochrane. Los resultados se informan de acuerdo con el consenso de Ítems Preferidos de Reporte en Revisiones Sistemáticas y Metaanálisis (Preferred Reporting Items for Systematic Reviews and Meta-Analyses, PRISMA, en inglés). La búsqueda se realizó el 1er de junio de 2020. Se identificaron e incluyeron estudios ex vivo de ciencia básica y estudios biomecánicos publicados, que evaluaran la magnitud y distribución de la presión en la interfase tendón-huella de las roturas del manguito rotador reparadas entre enero de 2015 y junio de 2020. Se realizaron búsquedas sistemáticas en las bases de datos MEDLINE, Embase, Scopus y Google Scholar utilizando los términos y operadores booleanos: (Rotator Cuff OR Supraspinatus OR Infraspinatus OR Subscapularis OR Teres Minor) AND Pressure AND Footprint. En la base de datos Embase, respetando su sintaxis, se utilizó: Rotator Cuff AND Pressure AND Footprint. RESULTADOS Un total de 15 de los 87 artículos encontrados cumplieron con todos los criterios de elegibilidad y se incluyeron en el análisis. CONCLUSIÓN La presión y área de contacto sería optimizada biomecánicamente con una reparación transósea de doble fila equivalente, sin nudos en la hilera medial, y con el uso de cintas para su ejecución, conceptos de reparación específica para roturas delaminadas, y limitación de la abducción en el postoperatorio inmediato.


OBJETIVE To provide a comprehensive synopsis and analysis of biomechanical studies on the magnitude and distribution of pressure at the tendon-footprint interface of rotator cuff tears reported in the literature in the last five years. METHODS The research was performed according to the methods described in the Cochrane Manual. The results are reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) consensus. The search was performed on June 1st, 2020. We identified and included ex vivo basic science studies and published biomechanical studies that evaluated the magnitude and distribution of pressure at the tendon-footprint interface of rotator cuff tears repaired between January 2015 and June 2020. Systematic searches on the MEDLINE, Embase, Scopus and Google Scholar databases were performed using the terms and Boolean operators: (Rotator Cuff OR Supraspinatus OR Infraspinatus OR Subscapularis OR Teres Minor) AND Pressure AND Footprint. In the Embase database, respecting its syntax, the following was used: Rotator Cuff AND Pressure AND Footprint. RESULTS In total, 15 of the 87 articles found fulfilled all the eligibility criteria and were included in the analysis. CONCLUSION The pressure and contact area would be biomechanically optimized with an equivalent transosseous double-row repair, without knots in the medial row, and with the use of tapes for its execution, specific repair concepts for delaminated tears, and a limitation of abduction in the immediate postoperative period.

ABSTRACT

OBJETIVO: Comparar la presión y el área de contacto en la interfase tendón-huella de una reparación realizada con suturas transóseas simples y cruzadas. MÉTODOS: Se utilizaron doce hombros de cordero para simular una rotura de manguito rotador. Se midió el área de contacto en la interfase tendón-huella con láminas sensibles a presión; luego, se midió la presión con un sensor digital. Se registró la presión basal durante la aplicación de carga cíclica y al final de la intervención. Se compararon 2 reparaciones: 2 túneles transóseos con nudos simples (TOS; n = 6) y 2 túneles transóseos con nudos cruzados (TOC; n = 6), utilizando FiberWire #2. Se realizaron 1.400 ciclos, con una frecuencia 2,5 Hz y una carga de 5 N. Se utilizó la prueba de Mann-Whitney, y ae consideraron significativos valores de p < 0,05. RESULTADOS: La reparación TOS presentó un 50,9 ± 12,7% distribución de presiones en comparación con 72,2 ± 5,3% en la reparación TOC (p < 0,009). La presión promedio en la reparación TOS fue 0,7 ± 0,1 MPa en comparación con 1,1 ± 0,2 MPa en la reparación TOC (p < 0,007). La reparación TOS registró una presión basal de 5,3 ± 5,3 N, presión final de 3,8 ± 4,6 N, y una variación de 51,7 ± 38%. La reparación TOC registró una presión basal de 10,7 ± 1,8 N, presión final de 12,9 ± 8,7 N, y una variación de 114,9 ± 65,9% (p < 0,044; p < 0,022; y p < 0,017, respectivamente). CONCLUSIÓN: La reparación TOC presenta mayor presión a nivel de la interfase tendón-hueso, menor pérdida de fuerza de contacto ante cargas cíclicas, y una mejor distribución de fuerza en la huella al comparar con la reparación TOS, lo que se podría traducir en mejor cicatrización tendínea.


OBJETIVE: To compare the pressure and contact area at the tendon-footprint interface of a repair performed with simple and crossed transosseous sutures. METHODS: Twelve lamb shoulders were used to simulate a rotator cuff tear. The contact area at the tendon-footprint interface was measured with pressure-sensitive films; then, the pressure was measured with a digital sensor. The baseline pressure was recorded during the application of a cyclic load and at the end of the intervention. A total of 2 repairs were compared: 2 transosseous sutures with single knots (STO; n = 6) and 2 transosseous sutures with crossed knots (TOC; n = 6) using FiberWire #2. In total, 1,400 cycles were performed, with a frequency of 2.5 Hz and a load of 5 N. The Mann-Whitney test was used. Values of p < 0.05 were considered significant.RESULTS: The TOS repair presented 50.9 ± 12.7% of pressure distribution compared to 72.2 ± 5.3% in the TOC repair (p < 0.009). The mean pressure in the TOS repair was of 0.7 ± 0.1 MPa compared to 1.1 ± 0.2 MPa in the TOC repair (p < 0.007). The TOS repair registered a basal pressure of 5.3 ± 5.3 N, a final pressure of 3.8 ± 4.6 N, and a variation of 51.7 ± 38%. The TOC repair registered a basal pressure of 10.7 ± 1.8 N, a final pressure of 12.9 ± 8.7 N, and a variation of 114.9 ± 65.9% (p < 0.044; p < 0.022; and p < 0.017 respectively).CONCLUSION: The TOC repair presents higher pressure at the tendon-bone interface, less loss of contact force under cyclic loads, and a better distribution of force on the footprint when compared with the TOS repair, which could translate into better tendon healing.

ABSTRACT

OBJETIVO: Comparar el desgaste óseo generado por la abrasión de una carga cíclica entre túneles clásicos oblicuos y perpendiculares. Nuestra hipótesis es la de que el túnel oblicuo presenta un menor desgaste óseo por abrasión cíclica comparado con el túnel perpendicular. MÉTODOS: Ocho hombros congelados de cordero fueron usados para el estudio biomecánico. En cada húmero proximal, dos túneles (oblicuo y perpendicular) fueron generados en la tuberosidad mayor. Se utilizó un sistema de tracción cíclica para traccionar hacia atrás y adelante una sutura trenzada en tensión a través del túnel, midiendo la distancia entre la entrada y la salida de la sutura en el túnel antes y después del proceso de ciclado como medida de perdida de tensión de la sutura. El resultado principal es el cambio de la distancia entre la entrada y la salida de la sutura en el túnel después del ciclado para estimar el desgaste óseo dentro del túnel. Para el análisis estadístico, se utilizó la prueba U de Mann-Whitney. Se consideraron significativos valores de p < 0,05. RESULTADOS: Los túneles perpendiculares tuvieron un 23,24 7,44% de pérdida de longitud, y los túneles oblicuos, 7,76 4,32%. La diferencia de pérdida de longitud fue significativa (p » 0,0003). CONCLUSIÓN: La abrasión ósea generada por el movimiento cíclico de la sutura en el túnel transóseo está influenciada por la geometría del túnel. El desgaste óseo es menor en un túnel oblicuo comparado con un túnel perpendicular. NIVEL DE EVIDENCIA: Estudio de ciencia básica


OBJETIVE: To compare the bone wear generated by the abrasion of a cyclic load between classic oblique and perpendicular tunnels. Our hypothesis is that the oblique tunnel is submitted to less cyclic abrasion bone wear compared with the perpendicular tunnel. METHODS: Eight fresh-frozen lamb shoulders were used for biomechanical testing. In each proximal humerus, two tunnels (one oblique and one perpendicular) were drilled at the greater tuberosity. We used a cyclic traction system to pull back and forth a braided suture under tension through the tunnel, measuring the distance between the entry and exit points of the suture within the tunnel before and after the cyclic process to release the tension in the suture. The main outcome was the percentage of change in the distance between the entry and exit points of the suture within the tunnel before and after cyclic abrasion to estimate the degree of bone wear inside the tunnel. For the statistical analysis, the Mann-Whitney U test was used. Values of p < 0.05 were considered significant. RESULTS: The perpendicular bone tunnels had 23.24 7.44% decrease in length, and the oblique bone tunnels, 7.76 4.32%. The difference in the decrease in length was significant (p » 0.0003). CONCLUSION: The bone abrasion caused by the cyclical movement of the suture in the bone tunnel was influenced by the shape of the tunnel. Bone wear was lower with an oblique tunnel compared with a perpendicular tunnel. LEVEL OF EVIDENCE: Basic Science Study

ABSTRACT

Introducción: Las fracturas metafisarias de radio distal son las fracturas más frecuentes en la edad pediátrica, siendo 30% del total de las mismas. Mantener la reducción de las fracturas desplazadas no siempre es posible: el re-desplazamiento es la principal complicación de estas lesiones. Clásicamente se realizó tratamiento con maniobra y yeso, aunque en los últimos años se asoció fijación con Kirschner wire (Kw) en búsqueda de disminuir el re-desplazamiento. El objetivo de nuestro trabajo es identificar factores de riesgo en búsqueda de realizar el mejor tratamiento siendo lo menos agresivo posible. Materiales y métodos: Se realizó una búsqueda sistematizada a través del buscador electrónico PubMed. La misma alcanzó un total de 4594 artículos, que de acuerdo con los criterios de inclusión y exclusión se seleccionaron 15 trabajos para realizar nuestra revisión bibliográfica. Resultados: Se destaca que la mayoría de los artículos encontrados son de nivel de evidencia III y IV. Nuestra búsqueda refleja un índice de re-desplazamiento entre 20-39% mediante yeso a las 2 semanas; asi como un índice de re-manipulación entre el 5-10 % del total de las fracturas desplazadas. La mayoría de los estudios analizados intentan identificar los factores de riesgo más importantes para el re-desplazamiento de las fracturas, de lo que se destacan el grado de desplazamiento inicial de la fractura y la reducción lograda de la misma. A su vez, otros artículos valoran los resultados del tratamiento mediante estabilización con yeso o fijación mediante Kirschner wire. Conclusión: el desplazamiento inicial de la fractura y la reducción lograda en block quirúrgico (BQ) son los factores de riesgo más importantes para el re-desplazamiento. Si bien la técnica de enyesado no es considerado una variable estadísticamente significativa, es considerada una variable importante en cuanto al pronóstico de la lesión, destacando al moldeado de 3 puntos como principal índice a considerar. Se considera aconsejable asociar un Kw en aquellas fracturas cabalgadas en las que no se logra una reducción anatómica en block quirúrgico.


Introduction: Distal radius metaphyseal fractures are the most frequent fractures in pediatric age, accounting for 30% of the total. Maintaining the reduction of displaced fractures is not always possible: re-displacement is the main complication of these injuries. Classically, treatment was performed with a maneuver and a cast, although in recent years fixation with Kirschner wire (Kw) has been associated in search of reducing re-displacement. The objective of our work is to identify risk factors in search of the best treatment while being the least aggressive possible. Materials and methods: A systematic search was carried out using the PubMed electronic search engine. It reached a total of 4594 articles, which according to the inclusion and exclusion criteria, 15 papers were selected for our bibliographic review. Results: It should be noted that most of the articles found are level of evidence III and IV. Our search reflects a re-displacement rate between 20-39% using a cast at 2 weeks; as well as a re-manipulation index between 5-10% of all displaced fractures. Most of the studies analyzed attempt to identify the most important risk factors for the re-displacement of fractures, of which the degree of initial displacement of the fracture and the reduction achieved are highlighted. In turn, other articles assess the results of treatment by stabilization with plaster or fixation with Kirschner wire. Conclusion: the initial displacement of the fracture and the reduction achieved in the surgical block (BQ) are the most important risk factors for re-displacement. Although the casting technique is not considered a statistically significant variable, it is considered an important variable in terms of the prognosis of the injury, highlighting the 3-point casting as the main index to be considered. It is considered advisable to associate a Kw in those mounted fractures in which an anatomical reduction in surgical block is not achieved.


Introdução: As fraturas metafisárias do rádio distal são as mais frequentes na idade pediátrica, correspondendo a 30% do total. Manter a redução das fraturas desviadas nem sempre é possível: o deslocamento é a principal complicação dessas lesões. Classicamente, o tratamento era realizado com manobra e gesso, embora nos últimos anos a fixação com fio de Kirschner (Kw) tenha sido associada na busca pela redução do deslocamento. O objetivo do nosso trabalho é identificar os fatores de risco em busca do melhor tratamento sendo o menos agressivo possível. Materiais e métodos: uma busca sistemática foi realizada usando o mecanismo de busca eletrônico PubMed. Chegou-se a um total de 4.594 artigos, que de acordo com os critérios de inclusão e exclusão, foram selecionados 15 artigos para nossa revisão bibliográfica. Resultados: Ressalta-se que a maioria dos artigos encontrados são de nível de evidência III e IV. Nossa pesquisa reflete uma taxa de re-deslocamento entre 20-39% usando um gesso em 2 semanas; bem como um índice de remanipulação entre 5-10% de todas as fraturas deslocadas. A maioria dos estudos analisados ​​busca identificar os fatores de risco mais importantes para o deslocamento das fraturas, que incluem o grau de deslocamento inicial da fratura e a redução alcançada. Por sua vez, outros artigos avaliam os resultados do tratamento com estabilização gessada ou fixação com fio de Kirschner. Conclusão: o deslocamento inicial da fratura e a redução alcançada no bloqueio cirúrgico (QB) são os fatores de risco mais importantes para o deslocamento. Embora a técnica de gesso não seja considerada uma variável estatisticamente significativa, é considerada uma variável importante em termos de prognóstico da lesão, destacando-se o gesso em 3 pontos como o principal índice a ser considerado. Considera-se aconselhável associar um Kw nas fraturas montadas em que não se consegue redução anatômica no bloqueio cirúrgico.

Introdução: O descarte do resíduo produzido é um dos grandes problemas mundiais; mensurar o quanto afeta a nossa saúde, a comunidade, o meio ambiente e o ecossistema é um desafio e diversas legislações tentam minimizar os danos causados pelo descarte inadequado e incorreto. O resíduo dos hospitais é denominado Resíduo de serviço de saúde (RSS) e deve ser tratado de acordo com a sua classificação, o explante ortopédico é um desses RSS e tem uma legislação própria para o seu manuseio e descarte desde 2012. Sempre que aparecem novas normatizações faz-se necessário a adequação do serviço de saúde e da equipe, as tecnologias podem ser utilizadas para auxiliar nesse processo. Refletindo sobre essas questões surgiu a questão que norteou o estudo: Seria possível desenvolver uma ferramenta eletrônica, do tipo aplicativo, para auxiliar no gerenciamento de explantes ortopédicos? Objetivos: Criar uma ferramenta eletrônica do tipo aplicativo para auxiliar no gerenciamento de explantes ortopédicos; criar protocolos que visem a institucionalização do fluxo de descarte dos explantes ortopédicos com base nas legislações e boas práticas vigentes e estabelecer um fluxo de acompanhamento de explantes ortopédicos a partir da necessidade da realização de uma cirurgia para a retirada de um implante ortopédico até a sua disposição final ambientalmente adequada. Metodologia: trata-se de uma pesquisa aplicada que visa o desenvolvimento de um software, do tipo aplicativo para smartphone, de cunho multiprofissional, para o gerenciamento de explantes ortopédicos. Para a elaboração do aplicativo foi seguido os conceitos de Pressman e suas definições quanto a fase de prototipação: comunicação, projeto rápido, modelagem do projeto rápido, construção do protótipo e emprego, entrega e alinhamento. Essas fases foram abordadas como etapas da pesquisa. O cenário do estudo foi um hospital-escola público integrante da rede de hospitais do Ministério da Educação. O público-alvo do estudo foi aquele a qual se destina a utilização da tecnologia, os gerentes, a equipe de enfermagem, os instrumentadores cirúrgicos do bloco cirúrgico do hospital-escola e os usuários do sistema de saúde submetidos a procedimentos cirúrgicos para retirada de explantes cirúrgicos. Resultados: Foram elaborados 8 (oito) produtos; dois em formato de artigo, o primeiro intitulado: "Gerenciamento de explantes ortopédicos e a realidade brasileira: uma revisão integrativa" e o segundo "A criação de aplicativo para auxílio no gerenciamento de explantes ortopédicos: uma realidade", 2 fluxogramas, 3 protocolos e um aplicativo intitulado "Explantes ortopédicos". O desenvolvimento do aplicativo foi realizado de forma interativa incremental, na linguagem de programação disponível no site da "Fábrica de aplicativos". Na fase de comunicação foram elaborados cinco documentos sendo eles dois formulários e três protocolos, além de dois fluxogramas que nos guiaram nas demais fases de criação do aplicativo. Conclusão: É possível criar uma ferramenta eletrônica do tipo aplicativo para auxiliar no gerenciamento de explantes ortopédicos assim como criar protocolos que visem a institucionalização do fluxo de descarte e acompanhamento desses para que tenham uma disposição final ambientalmente adequada


Introduction: Disposal of waste produced is one of the world's major problems; measuring how much it affects our health, community, environment and ecosystem is a challenge and various laws try to minimize the damage caused by improper and incorrect disposal. The waste of hospitals is called Health Service Residue (RSS) and should be treated according to their classification, the orthopedic explant is one of these RSS and has its own legislation for its handling and disposal since 2012. Whenever new norms appear, it is necessary to adapt the health service and the team, the technologies can be used to assist in this process. Reflecting on these questions, the question that guided the study arose: Would it be possible to develop an electronic tool, of the application type, to assist in the management of orthopedic explants? Objectives: Create an electronic tool of the type application to assist in the management of orthopedic explants; create protocols aimed at the institutionalization of the disposal flow of orthopedic explants based on the laws and good practices current and establish a follow-up flow of orthopedic explants from the need for surgery for the removal of an orthopedic implant until its final disposal is environmentally appropriate. Methodology: this is an applied research that aims at the development of a software, type smartphone application, of a multiprofessional nature, for the management of orthopedic explants. For the elaboration of the application was followed the concepts of Pressman and its definitions regarding the prototyping phase: communication, fast design, rapid design modeling, prototype construction and employment, delivery and alignment. These phases were addressed as stages of the research. The study scenario was a public teaching hospital that is part of the hospital network of the Ministry of Education. The target audience of the study was the one that was intended to use the technology, managers, the nursing team, surgical instruments of the surgical block of the teaching hospital and users of the health system submitted to surgical procedures for removal of surgical explants. Results: Eight (8) products were elaborated; two in article format, the first entitled: "Management of orthopedic explants and the Brazilian reality: an integrative review" and the second "The creation of an application to assist in the management of orthopedic explants: a reality", 2 flowcharts, 3 protocols and an application entitled "Orthopedic Explants". The development of the application was carried out interactively incrementally, in the programming language available on the "Application Factory" website. In the communication phase, five documents were elaborated, two forms and three protocols, in addition to two flowcharts that guided us in the other phases of application creation. Conclusions: It is possible to create an electronic tool of the application type to assist in the management of orthopedic explants as well as to create protocols that aim at the institutionalization of the disposal flow and monitoring of these so that they have an environmentally appropriate final disposition

ABSTRACT

The Coronavirus pandemic (COVID-19) triggered a global health emergency, and as a response, institutions and medical services have implemented different measures regarding the management of these patients in order to maintain medical care, and reduce the spread of the virus in patients and medical staff. The following review aims to present the current recommendations made by international, national and local societies regarding medical action from Traumatology and Orthopaedics. A literature review was done on Medline / Pubmed platforms, The Journal Bone and Joint Surgery (JBJS), Journal of the American Academy of Orthopedic Surgeons (JAAOS), Sociedad Chilena de Ortopedia y Traumatología (SCHOT). The literature was in Spanish and English, comparing it with reality on a local level. The current COVID-19 pandemic led to the complete reform of the trauma care units, starting with the development of subspecialty teams that rotate periodically, which are in charge of the emergency area, treating patients with all personal protection elements (PPE) and categorizing those patients who require emergency trauma surgery, from those that can be managed in a delayed manner. Regarding patients who are hospitalized, a COVID-19 PCR (Polymerase Chain Reaction) test is taken as screening, except for emergency surgeries where all intraoperative protection measures are taken. In addition, for greater safety, all elective surgery was suspended, which reduces the flow of patients in the ward and in the inpatient unit. Outpatient care was optimized in order to protect patients in their periodic check-ups.

ABSTRACT

Abstract Background: Tranexamic acid was studied in four different dosage regimens and their efficacy was compared for perioperative blood loss reduction, blood transfusion requirements and deep vein thrombosis (DVT) complication. Methods: Two hundred patients undergoing major orthopedic procedures were divided into five groups containing 40 patients each: Placebo, low dose (bolus 10 mg kg-1), low dose + maintenance (bolus 10 mg kg-1 + maintenance 1 mg kg-1 hr-1), high dose (bolus 30 mg kg-1) and high dose + maintenance (bolus 30 mg kg-1 + maintenance 3 mg kg-1 hr-1). Surgical blood loss was measured intraoperatively and drains collection in the first 24 hours postoperatively. Blood transfusion was done when hematocrit falls less than 25%. DVT screening was done in the postoperative period. Results: The intraoperative blood loss was 440 ± 207.54 mL in the placebo group, 412.5 ± 208.21 mL in the low dose group, 290 ± 149.6 ml in the low dose plus maintenance group, 332.5 ± 162.33 mL in the high dose group and 240.7 ± 88.15 mL in the high dose maintenance group (p < 0.001). The reduction in postoperative blood loss in the drain for first 24 hours was 80 ± 44.44 mL in the placebo group, 89.88 ± 44.87 mL in the low dose group, 56.7 ± 29.12 mL in the low dose plus maintenance group, 77.9 ± 35.74 mL in the high dose group and 46.7 ± 19.9 mL in the high dose maintenance group (p < 0.001). DVT was not encountered in any patient. Conclusion: Tranexamic acid was most effective in reducing surgical blood loss and blood transfusion requirements in a low dose + maintenance group.


Resumo Justificativa: O ácido tranexâmico foi avaliado em quatro esquemas com diferentes posologias, comparando-se a eficácia de cada esquema quanto a redução na perda sanguínea perioperatória, necessidade de transfusão sanguínea e ocorrência de Trombose Venosa Profunda (TVP). Método: Duzentos pacientes submetidos a procedimentos ortopédicos de grande porte foram divididos em cinco grupos de 40 pacientes de acordo com o esquema de administração de ácido tranexâmico: grupo placebo, grupo baixa dose (bolus de 10 mg.kg-1, grupo baixa dose e manutenção (bolus de 10 mg.kg-1 + manutenção de 1 mg.kg-1.h-1), grupo alta dose (bolus de 30 mg.kg-1), e grupo alta dose e manutenção (bolus de 30 mg.kg-1 + manutenção de 3 mg.kg-1.h-1). A perda sanguínea cirúrgica foi medida no intraoperatório. Além disso, nas primeiras 24 horas pós-operatórias, foi medido o volume de sangue coletado no dreno. Era realizada transfusão de sangue se o valor do hematócrito fosse inferior a 25%. Foi realizada avaliação quanto à ocorrência de TVP no pós-operatório. Resultados: A perda sanguínea intraoperatória foi de 440 ± 207,54 mL no grupo placebo, 412,5 ± 208,21 mL no grupo baixa dose, 290 ± 149,6 mL no grupo baixa dose e manutenção, 332,5 ± 162,33 mL no grupo alta dose, e 240,7 ± 88,15 mL no grupo alta dose e manutenção (p < 0,001). A redução na perda sanguínea pós-operatória pelo dreno nas primeiras 24 horas foi de 80 ± 44,44 mL no grupo placebo; 89,88 ± 44,87 mL no grupo baixa dose, 56,7 ± 29,12 mL no grupo baixa dose e dose de manutenção, 77,9 ± 35,74 mL no grupo alta dose e 46,7 ± 19,9 mL no grupo alta dose e manutenção (p < 0,001). TVP não foi observada em nenhum paciente. Conclusão: O ácido tranexâmico administrado em baixa dose combinado à manutenção foi mais eficaz em reduzir a perda sanguínea cirúrgica e a necessidade de transfusão de sangue.

ABSTRACT

Abstract The erector spinae plane block is a safe and effective regional anesthesia technique, which has earned new indications perioperatively since its description. We introduce two pediatric anesthesia cases in which we performed the erector spinae plane block during intermediate/major orthopedic surgeries. The first patient is a 2 year-old girl submitted to surgical treatment of developmental dysplasia of the hip. The second patient is a 14 year-old boy submitted to surgical treatment of bilateral clubfoot. This last patient is potentially the first published case in which the erector spinae plane block was performed for ankle and foot surgery. Both cases experienced excellent analgesia, avoiding opiate requirement completely.


Resumo O bloqueio do plano eretor da espinha guiado por ultrassonografia é uma técnica segura e eficaz de anestesia regional, que apresenta novas indicações no perioperatório. Apresentamos dois casos de bloqueio do plano eretor da espinha realizados para analgesia de cirurgia ortopédica pediátrica de médio/grande porte. O primeiro: menina de 2 anos submetida a tratamento cirúrgico de displasia do desenvolvimento do quadril. O segundo: menino de 14 anos submetido a correção de pé valgo bilateral. Este último, no melhor do nosso conhecimento, é o primeiro caso de bloqueio do plano eretor da espinha em cirurgia de tornozelo/pé descrito na literatura. Os casos tiveram analgesia pós-operatória adequada, sem necessidade de opioides.

ABSTRACT

Resumen Objetivo Comunicar la experiencia en el tratamiento de pectus excavatum en el Instituto Nacional del Tórax. Material y Método: Estudio descriptivo con seguimiento. Se recolectaron datos de las variables de interés, mediante la revisión de fichas clínicas. Se incluyeron pacientes operados entre marzo de 2007 y abril de 2018. Resultados Se incluyeron 86 pacientes operados con técnica mínimamente invasiva en el período descrito. De ellos, 74 pacientes de sexo masculino. El promedio de edad al momento de la cirugía fue de 17,8 años. El principal motivo de consulta fue por desmedro estético que correspondió al 41,8% de los pacientes. Salvo en 1 paciente, en todo el resto se ocupó una sola barra. En nuestra serie hubo 12 pacientes que presentaron alguna complicación operatoria y 1 paciente fallecido. Hasta el cierre del seguimiento se retiraron 61 barras, 2 de ellas previo al período estipulado de tratamiento, por morbilidad. Hay 20 barras in situ y 4 pacientes de los cuales no se tiene registro por abandono de controles. Discusión El pectus excavatum es la más frecuente de las deformidades de la pared torácica, es 4 a 6 veces más frecuente en hombres que en mujeres. En general los pacientes son asintomáticos, aunque algunos pueden presentar síntomas cardiopulmonares. La reparación con cirugía mínimamente invasiva con técnica de Nuss aparece hoy en día como el gold standard de manejo. Conclusión El manejo de los pacientes con pectus excavatum en nuestra Institución se asemeja a lo reportado en la literatura internacional. Nuestros esfuerzos deben apuntar a disminuir la morbimortalidad asociada.


Aim To communicate the experience in the treatment of pectus excavatum in the National Institute of Thorax. Materials and Method: Descriptive study with follow-up. Data of variables of interest were collected through the review of clinical records. Patients operated between March 2007 and April 2018 were included. Results 86 patients operated with the Nuss technique were included in the period described. Of them, 74 male patients. The average age at the time of surgery was 17.8 years. The main reason for consultation was due to cosmetic detriment that corresponded to 41.8% of the patients. Except in 1 patient, in all the rest a single bar was occupied. In our series, there were 12 patients who presented some operative complication and 1 patient died. Up to the end of the follow-up, 61 bars were removed, 2 of them in non-scheduled surgery. There are 20 bars in situ and 4 patients of which there is no registration due to abandonment of controls. Discussion Pectus excavatum is the most frequent of the deformities of the chest wall, it is 4 to 6 times more frequent in men than in women. In general, patients are asymptomatic, although some may have cardiopulmonary symptoms. The repair with minimally invasive surgery with Nuss technique appears today as the goldstandard of management. Conclusion The management of patients with pectus excavatum in our Institution is similar to that reported in the international literature. Our efforts should aim to reduce the associated morbidity and mortality.

ABSTRACT

Abstract Tarsal navicular fractures, as well as other midfoot injuries, are rare, and can result in severe impairment if not properly treated. Parkour, a modern sport, is gaining popularity among young individuals in urban areas, and is prone to result in high-energy trauma, which is scarcely described in the literature. The following is a report of a rare case of tarsal navicular fracture in a 17-year-old male, sustained during parkour practice, which was treated successfully with open reduction and internal fixation. The description of the case emphasizes the challenges of its approach; the discussion highlights the treatment options and goals. The case should also raise awareness about the increasing occurrence of these uncommon lesions.


Resumo As fraturas do escafoide társico, bem como outras lesões do médiopé, são raras e podem resultar em incapacidade grave se não forem tratadas adequadamente. Parkour, um esporte moderno, está ganhando popularidade entre os jovens em áreas urbanas, e é propenso a traumatismos de alta energia, sendo estes escassamente descritos na literatura. O presente relato trata de um caso de fratura rara do escafoide társico em um paciente do sexo masculino de 17 anos, ocorrida durante a prática de parkour, que foi tratada com sucesso, com redução aberta e fixação interna. A descrição do caso enfatiza os desafios na sua abordagem; a discussão destaca as opções de tratamento e seus objetivos. O caso também deve alertar sobre a ocorrência crescente dessas lesões incomuns.

ABSTRACT

Abstract Background and objectives Ultrasound-guided internal jugular vein catheterization is a common and generally safe procedure in the operating room. However, inadvertent puncture of a noncompressible artery such as the subclavian artery, though rare, may be associated with life-threatening sequelae, including hemomediastinum, hemothorax, and pseudoaneurysm. Case report We describe a case of the successful endovascular repair of right subclavian artery injury in a 75-year-old woman. Subclavian artery was injured secondary to ultrasound-guided right internal jugular vein catheterization under general anesthesia for orthopedic surgery. Conclusion Under general anesthesia several factors such as hypotension can mask the signs of subclavian artery injury. This case report indicates that clinicians should be aware of the complications of central venous catheterization and take prompt action.


Resumo Justificativa e objetivos A cateterização da veia jugular interna guiada por ultrassom é um procedimento comum e geralmente seguro em sala cirúrgica. No entanto, a punção inadvertida de uma artéria não compressível, como a artéria subclávia, embora rara, pode estar associada a sequelas e risco para vida, incluindo hemomediastino, hemotórax e pseudoaneurisma. Relato de caso Descrevemos um caso bem-sucedido da correção endovascular de lesão da artéria subclávia direita em uma paciente de 75 anos. A artéria subclávia foi lesionada após cateterização guiada por ultrassom da veia jugular interna direita sob anestesia geral para cirurgia ortopédica. Conclusão Sob anestesia geral, vários fatores, como a hipotensão, podem mascarar os sinais de lesão da artéria subclávia. Este relato de caso indica que os médicos devem estar cientes das complicações da cateterização venosa central e tomar medidas imediatas.
